Will I have a bolt/scope contact problem?
 

Wanting to have a custom rifle built off of a Rem. 700 action.

I also typically prefer Leupold low rings.

Going to use a Leupold VX-III 3.5-10X40

I know the 40mm. objective will clear the barrel, but should I expect the 90 degree bolt throw to contact the eyepiece of the scope when the bolt is raised?

Yes,I was going to use low rings,but when i cycled the bolt it scraped the side of the scope.Ordered med height rings,works like a charm.rem 700 243

Most likely you will, I'd suggest Medium rings to play it safe.

No problems for me either...................

It depends on the stock you choose, lows might be to low if you get a higher comb stock...I had to use mediums with a B&C thumbhole stock to be comfy and highs would actually be a little better when using ear muffs...lows were miserable...

I personally don't believe the 40mm will clear the barrel unless you push it way far forward. But I know for a fact, the bolt will not contact the scope

I'm using medium weaver rings on my 700 SPS.I have a nikon buuckmaster 3x9 40mm. It barely clears the scope,but I like my scope mounted as low as possible.

the 40mm objective will clear the barrel.....possibly because I mount my scopes a tad further forward than average.
I mount them as far forward as possible where I still get a full field of view when at full magnification. It also gives me a little mental comfort when shooting heavy recoiling rifles that I wont get caught over the eye with the scope.

Maybe, but does your cheek weld correctly? I mean for me, low would be too low with a monte carlo type stock.
